I notice the new release of Fallout is up but unlike the original release there is no Mac client to download if you purchase it.

Is this a temporary situation or are we unlikely to see an updated Mac released also?

Thanks.

I want to know too... but gog answer that for now they don't know.

I too am stuck on a Mac, for now. The burning question is do I purchase the package now at a reasonably discounted price and attempt the Wine/Crossover route, or lay low and keep my fingers crossed...

the old version was already a wineskin port.
I suggest you to just download wineskin and make your port with the windows installer (since fallout is an old game it must be easy)... just go on winehq and read if this game need winetricks or need a specify version of wine.
if you have problem with wineskin port (that is the best option... because you get a .app), you can use playonmac

Great info! I did purchase them recently on Steam (at the time GOG no longer carried them) and could not get them to run. That could very well be my lack of experience using Wineskin. If the GOG version is a better bet, I could stand spending the $10...

no, it's steam... it's really difficult to port. just try an already made wrapper (playonmac nd portingteam/paulthetall/portingkit have a good steam port).

Outstanding, thanks LiefLayer!

you're welcome.
if you will need help in the future with some game write me in private. if I have it I will tell you if it is possible to port it.
for now you cannot port the games that use DirectX 12 because wine does not support them yet (the witcher 3, batman arkham knight, dragon age inquisition for example).

you mean dx11? dx12 isn't out :) latest version of wine just released a preliminary version of dx11, but I doubt it is useful yet.

i mean that games that use dx11-12 cannot use wine.
I thought they were already out with Windows 10.

If there's a choice to be made between a Windows emulator and Bootcamp running Windows 10 natively on your Mac, the later has surely got to be easier to setup and a far better performer than a Windows emulator/translator running on OS X. With Bootcamp you not only run Windows natively just as OS X runs on your Mac, you can also run D3d/DX games on your Mac without emulation--not to mention OpenGL ~4.4/5 games under Windows (whereas OS X is still @ OpenGL 3.x--last I checked with Valve.)

The only possible fly in the ointment is that Apple's not so hot with some Windows drivers, and Bootcamp Windows drivers need to come from Apple, but in many cases the Mac is so x86 bog-standard these days that you can run the manufacturer's drivers (just like you would in any Windows box.) Just thought I'd mention it...software emulation is fine for word processors and spread sheets and browsers and other non-demanding software, but you don't want to depend on it to run demanding 3d games--it would be both buggy and objectionably slow. There are a few non-demanding games, older games, that might run fine on an emulator--maybe--but since you have a choice in the matter I would think Bootcamp would be far more attractive...

wine is not an emulator (Wine (originally an acronym for "Wine Is Not an Emulator") https://www.winehq.org/about/ ), it only translate open gl calls to directx calls, that means almost native performance.
virtualizzation is not emulation too... because when you emulate you emulate the cpu too... like when you emulato a nds you emulate an arm cpu on a x86 one. worst performance then wine but better then emulation.
bootcamp is easier but you need to keep lots of space in your internal disk (and if you have an SSD is worst), using wine you only use the space for the application + wine, using virtualization you can put the virtual machine on a external drive.
Also you need to restart your computer using bootcamp.
Also you don't need so much power to run games like fallout, and many modern games (2012-2013) got a mac version (like metal gear rising, pillars of eternity, hitman absolution etc, and many will get one soon like trine 3 and evoland 2 (I wish for the witcher 3 too since there is a mac version of the wicher 1 and 2 that use eON a tecnology that is more native then wine but not native yet XD)....
Also if you have a macbook you still need the new one to run the witcher 3 (if you are really lucky).
OSX from Mavericks use Open GL 4.1 not 3.x anymore.

there are so many errors on your message, you clearly don't use mac, or you use wrong information.
well, I can say to you that all the games I have on gog works great on my macbook, native and wineskin one, no strange bugs. also i ported many modern games, like dark souls, dragon age origins (but there is also a wineskin official port of the 2), batman arkham origins.

Another thing, Wine doesn't have the overhead on your computer that virtualization has of booting up a second os at the same time, not to mention the diskspace... And is a lot less annoying then rebooting your computer just to play a game. And you don't need to own windows, or a copy of VMWare/Paralles all of which costs significant money!
Also wine actually has much better compatibility for older windows software then windows 10 does. Especially anything running earlier directx than 9. This is why there is an effort to get wine working on windows. (no idea how far along that is though)

As for 12 out on windows 10, not on release. that comes later. Though I'm sure there are a few developers working with an early copy. (though this is out of my rear-end and should not taken as statement of fact)
